이진 데이터에서 * .bmp 이미지 만들기

Question

VB6을 사용하여 픽셀 당 1 비트를 사용하여 * .bmp 이미지를 만드는 방법은 무엇입니까? 예제 프로젝트가 이런 식으로 존재합니까?

'#    # Image Data Info :           # 
'#    #    Each black dot are represented as binary 1(high)# 
'#    #    and white are represented as binary 0(low) in # 
'#    #    form of hexadecimal character.     # 
'#    # Example  : (for this example assume the image width is 8)# 
'#    #    Data  : 7E817E       # 
'#    #    Binary data : 7=0111, E=1110, 8=1000, 1=0001 # 
'#    #        7=0111, E=1110     # 
'#    #    Image data : px1 px2 px3 px4 px5 px6 px7 px8 # 
'#    #       px1 w b b b b b b w # 
'#    #       px2 b w w w w w w b # 
'#    #       px3 w b b b b b b w # 
'#    #                # 
'#    #       w = white, b = black, px = pixel # 

세부 사항 :

Answer 1

다음과 같은 코드를 사용할 수 있음을 유의하시기 바랍니다 :

• 이미지 너비가 8의 배수 여야합니다;
• 행은 맨 아래부터 시작합니다.

요구 사항이 적절하지 않은 경우 적절하게 코드를 수정할 수 있습니다.
